Hi,
I think Google Cloud SQL 2nd generation is inaccessible now.
I tried to connect from GCE instances to Cloud SQL via Cloud SQL Proxy, but I cannot connect.
This happened when I restarted Cloud SQL instance (with changing instance spec) at about June 11, 15:00 UTC (June 12, 00:00 JST).
I updated my.cnf variables and machine specs for several times, and just restarted instance for several times.
It takes so long (5 - 10 mins) to complete restart. I viewed Stackdriver logging page [
https://console.cloud.google.com/logs ] and saw ton of warnings.
In the operations tab [
https://console.cloud.google.com/sql/instances/INSTANCE_NAME/operations ], there are several "An unknown error occurred" logs on restart and update.
Next, I gave up to continue with Google Cloud SQL and get back to our old server instance which is hosted by another cloud vendor.
To keep data, I tried to export current data with export button in the overview page of Cloud SQL instance [
https://console.cloud.google.com/sql/instances/INSTANCE_NAME/overview ]
I saved it in SQL format, but the file is 0 byte and empty.
In the operation page, I found following error message:
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/mysql/mysql.sock' (111) when trying to connect
Thanks in advance.
